Abstract: A three-dimensional semiconductor device is provided as follows. A substrate includes a contact region, a dummy region, and a cell array region. A stack structure includes electrodes vertically stacked on the substrate. The electrodes are stacked to have a first stepwise structure on the contact region and a second stepwise structure in the dummy region. Ends of at least two adjacent electrodes in the second stepwise structure have first sidewalls vertically aligned so that horizontal positions of the first sidewalls are substantially the same.

Abstract: A semiconductor device includes a first substrate, circuit elements, lower interconnection lines, a second substrate, gate electrodes stacked on the second substrate to be spaced apart from each other in a first direction and forming first and second stack structures, channel structures penetrating through the gate electrodes, and first and second contact plugs penetrating through the first and second stack structures, respectively, and connected to the gate electrodes. The first stack structure has first pad areas in which the gate electrodes extend further than upper gate electrodes, respectively, and are connected to the first contact plugs, respectively. The second stack structure has second pad areas in which the gate electrodes extend further than upper gate electrodes, respectively, and are connected to the second contact plugs, respectively. The first and second pad areas are offset in relation to each other so as not to overlap each other in the first direction.
